Match

Match[Lag,EFTOrder 6,LoopOrder 1]

returns the EFT Lagrangian resulting from integrating out the heavy fields from the Lagrangian Lag. The optional arguments EFTOrder and LoopOrder determine, respectively, the desired order in the EFT and loop expansion, with LoopOrder admitting the values 0 (tree), {1} (loop) or 1 (tree+loop).

Details and Options

  • The following options can be given:
  • EFTOrder6EFTOrder is an option for various routines specifying the targeted order in power-counting, as well as defining the power-counting of couplings.
    LoopOrder1LoopOrder is an option for Match routine specifying the targeted order in the loop expansion. It can take the values 0 (tree), {1} (loop) or 1 (tree+loop).
